Revision as of 10:52, 26 August 2011

The Hockey Stick Hoax[1] was perpetrated by Michael Mann in the form of a fraudulent[2] reconstruction of the Earth's atmosphere temperature created by Michael Mann from various proxies such as tree rings, superimposed on the record of thermometer readings from ground-based weather stations. The proxy estimates go back 1,000 years, while the thermometer readings date from 1850. It was used to justify the anthropogenic global warming theory (AGW), but the fraud was exposed by two Canadian statistics experts. Mann's graph, which was shaped like a hockey stick, portrayed temperatures as steadily declining since medieval times and then sharply rising in the last century and a half. Notably, his reconstruction fueled claims that 1998 and following years had the highest temperatures in 1,000 years.

Deceit

Michael Mann's hockey stick chart was obviously false. Because of its deceitful appearance, many scientists protested Mann's graph and the data behind it. However, Mann initially refused to reveal any of his data or methods - even though his work was supported by the U.S. government - which made it exceedingly difficult for other scientists to replicate his work.

In the case of the Mann et al [1998,1999] study, used for the IPCC's 'hockey stick' graph, Mann was initially unable to remember where the data was located, then provided inaccurate data, then provided a new version of the data which was inconsistent with previously published material, etc. The National Post has recently reported on my experience as this unfolded.[3]

Eventually, McIntyre and McKitrick learned enough about Mann's data and methods to discover where he went wrong. But the political climate made it very difficult for the correct information to find a publisher.
